detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1 , it is a flow chart of a body correction reminding method provided by Embodiment 1 of the present invention. A kind of body correction reminding method as described in Figure 1, comprises steps:

S11. Obtain in real time the relative distance between each of the m position sensors placed on the user and the other position sensors; wherein, m<100;

S12. Based on the threshold value of the relative distance between any two position sensors obtained in advance, determine whether the relative distance between any two position sensors exceeds the upper limit threshold or is lower than the lower limit threshold at any time; wherein, the relative distance between any two position sensors The threshold of is obtained through the predetermined critical body state; when the relative distance between any two position sensors in the standard body state is greater than the relative distance between the corresponding two position sensors in the critical body state, the corresponding two position sensors The threshold is the lower limit threshold; when the relative distance between any two position sensors in the standard body state is less than the relative distance between the corresponding two position sensors in the critical body state, then the threshold of the relative distance of the corresponding two position sensors is the upper threshold;

The standard body state is a standard state in which the user's posture is correct. This state can be set as a reference posture, and the user can perform a corresponding posture according to the reference posture. At this time, the user can be considered to be in the standard body state, and the relative position of each position sensor is recorded at this time; The critical body state is a state where the user is close to losing shape. In this state, another reference posture can be set, and the user can perform a corresponding posture according to the other reference posture. At this time, the user can be considered to be in a critical body state.

S13. If there are a preset relative distances exceeding the upper limit threshold or lower than the lower limit threshold at any time, start recording the duration of the a relative distances exceeding the upper limit threshold or lower than the lower limit threshold; and 1<a< m(m-1)/2;

The preset a relative distances are a relative distances of several position sensors, and the value of a can be set by the system or customized by the user according to their own needs. When the a relative distance exceeds the upper threshold or falls below When the lower threshold is reached, the user can be considered to be in a state of incorrect posture, at which point the duration of this state can be started to be counted.

S14. When the duration of the a relative distances exceeding the upper threshold or lower than the lower threshold exceeds the preset time threshold, send a control signal to control the stimulating electrodes on the position sensor to start working to remind the user to perform body correction.

In this step, the time threshold can be set by the system or customized by the user. If the set time threshold is too short, it will cause the user to send a wrong reminder signal when temporarily adjusting the body state, that is, the setting of the time threshold should satisfy the user in a state of long-term incorrect posture before reminding the user to correct the body.

Referring to FIG. 2 , it is a flowchart of a body correction reminding method provided by Embodiment 2 of the present invention. A kind of shape correction reminding method as described in Figure 2, on the basis of embodiment 1, also includes steps:

S21. When the duration of the a relative distance exceeding the upper limit threshold or being lower than the lower limit threshold exceeds a preset time threshold, display a reminder message on the display screen to remind the user to perform body correction.

Referring to FIG. 3 , it is a flowchart of a body correction reminding method provided by Embodiment 3 of the present invention. A kind of body correction reminding method as described in Figure 3, on the basis of embodiment 1, also includes steps:

S31. Obtain the position information of each of the position sensors, establish and display a space model describing the position information based on the acquired position information of each of the position sensors; the space model includes symbol;

S32. If any of the relative distances exceeds the upper limit threshold or is lower than the lower limit threshold at any time, mark the symbol of the position sensor corresponding to the relative distance on the space model.

The implementation process and working principles of the above-mentioned several embodiments will be described in detail below with reference to FIG. 4 . The m position sensors 1 are closely attached to the user's body at a certain interval, each of the position sensors 1 transmits its position information to the terminal device, and the terminal device carries out the position information of each of the above position sensors 1 After processing, the relative distance of each position sensor is obtained. When the user adjusts the body in a standard body state, collect the position information of each sensor 1 and obtain the relative distance of each sensor 1; when the user adjusts the body in a critical body state, collect the position information of each sensor 1 and obtain relative distance. Wherein, the threshold value of the relative distance between any two position sensors 1 is obtained through a predetermined critical body state; on the other hand, when the relative distance between any two position sensors 1 in the standard body state is greater than When corresponding to the relative distance of two described position sensors 1, then the threshold of corresponding two described position sensors 1 is the lower limit threshold value; When the relative distance 1 of any two described position sensors under the standard form state is less than the critical form When the relative distance between the two corresponding position sensors 1 is the corresponding relative distance, the threshold of the relative distance between the corresponding two position sensors 1 is the upper threshold. When there are preset a relative distances exceeding the upper limit threshold or lower than the lower limit threshold at any moment, start recording the a relative distances for the duration of exceeding the upper limit threshold or lower than the lower limit threshold; when the a relative distance exceeds When the duration of the upper threshold or lower than the lower threshold exceeds the preset time threshold, the stimulating electrodes on the position sensor 1 are controlled to start working to remind the user to perform body correction. Through the above process, the position sensor 1 can be fixed at any position, and the criterion for judging the threshold is not fixed, but is set according to the individual user and the position of each position sensor 1, which is more scientific and reasonable, and is suitable for different users' physical conditions. To prevent misjudgment and false reminders.

Preferably, when the duration of the a relative distance exceeds the upper limit threshold or is lower than the lower limit threshold exceeds the preset time threshold, a reminder message can be sent to remind the user to perform body correction, which serves as a further reminder and has more powerful functions .

Further, a space model can be established through the position information of each position sensor 1, and if any of the relative distances exceeds the upper limit threshold or is lower than the lower limit threshold at any time, the relative distance is marked on the space model. The distance corresponds to the sign of the position sensor 1. The user can monitor the deformation of the body through the spatial model. Even if no reminder signal is issued, the corresponding part can be corrected by observing the deformed area. It is simple and clear, and helps the user to obtain a good sense of experience.

Referring to FIG. 5 , it is a flowchart of a body correction reminding method provided by Embodiment 4 of the present invention. Kind body correction reminding method as described in Figure 5, on the basis of embodiment 1 also comprises steps:

S41. If there is a relative distance exceeding the upper limit threshold or lower than the lower limit threshold at any time, judge whether the relative distance exceeds the preset 1/b times the upper limit threshold or is lower than the preset 1/b times the lower limit threshold ;

It can be understood that the value of b can be set by the system, and can also be customized by the user according to their own needs. When the relative distance between any two position sensors exceeds the upper limit threshold or is lower than the lower limit threshold, the purpose of setting 1/b times the upper limit threshold or the lower limit threshold as the criterion for judging whether it is abnormal is: when the relative distance between any two position sensors When there is only a small deviation in the distance, it can be considered that the user is still in a correct posture, and no reminder signal is sent to remind the user to correct the body; when there is a large deviation in the relative distance between any two position sensors, it can be considered that the user is in an incorrect posture. state, the user needs to be reminded to correct the shape.

S42. If it is determined that the relative distance exceeds the preset 1/b times the upper threshold or is lower than the preset 1/b times the lower threshold, and the relative distance exceeds the preset 1/b times the upper threshold or When the duration of the lower limit threshold lower than the preset 1/b times exceeds the preset time threshold, a control signal is sent to control the stimulating electrodes on each of the position sensors to start working.

During specific implementation, when a large deformation occurs in a certain part of the human body, there is a relative distance that is higher than the upper threshold or lower than the lower threshold in a larger range, and the upper threshold or lower threshold of 1/b times the preset value is Standard, then control the stimulation electrodes to start working to remind the user to perform body correction. The above method is suitable for reminding the user when a certain part of the human body is greatly deformed, which is more scientific and reasonable, and the function tends to be more perfect. In this embodiment, when multiple relative distances are higher than the upper threshold or lower than the lower threshold, reference may be made to the implementation process of Embodiment 1, which will not be repeated here.
